Creating Your First Lisp Project - Quicklisp, asdf, and Packages

In this tutorial, we will create a simple REST API in Common Lisp and learn about Quicklisp and asdf. You will know everything needed to create a professional Lisp library or executable by the end.

Beyond Mars -level cli setup... slick.

[@gnorts_mr_alien]

Thank you Gavin, you consistently produce the best CL content for people on the path to becoming intermediate lispers. Very appreciated.

[@jimlawson629]

Gavin, thank you so much for all the recent Lisp content! This sort of info is hard to come by in video format. Looking forward to another video.

[@GavinFreeborn]

My pleasure! There is plenty more where that came from.

[@emoutraspalavras-marloncou4459]

I love LISP... it is amazing. Thank you for the contents. I hope there will be more similar material in the near future.

[@GavinFreeborn]

Indeed there is haha might be coming out a little late this week but still coming

[@AzerAnimations]

This is actually the exact type of video I was looking for!

[@ArmeroPR]

Glad I found your channel. Subbed.

[@caddr]

thank you, I want to learn asdf but the asdf manual was confusing me, this video made my confusion go away

[@user-ui8my9zs7o]

Please make more lisp content!

[@trannusaran6164]

I actually basically rebuilt cl-cookieproject within cl-project's templating system. Very nice system fukamachi set up, not sure who to contribute that to, lol

[@GavinFreeborn]

Would love to see that since I haven't gotten a chance to do that haha. I did realize that it had one just never got into understanding it 😅

[@farsthary1984]

love your voice

[@user-zx3vp8mw7d]

i am learning lisp. Do you have any notes/tutorial on how to build non-web simple application. For example- i want to create a package, add calculator class with basic operations.. and make a executable from it. ?

[@doesnt_even_lift]

Is there any chance you'd consider doing a video on how to develop TUI applications with croatoan or similar? I've never figured out how to make curses libraries mesh well with repl-driven development

[@GavinFreeborn]

Sure. I would definitely be open to making such a video. I've just hardly had the time to record a video recently. I have a few videos on the backlog but this is definitely worth tackling

[@chocoblan4288]

i love lisp, but my brain doesn't. haha

[@KoltPenny]

Ironclad refuses to install for some reason :(

[@os4764]

Hi thanks for the tutorial. I have a question, I created a web-project and then when I go to static/css to change the color of h1 for example to 'red', I don't see the change on the page. My question is very simple: do I re-compile a file in order for the changes to take effect? In this case, do I re-compile the web.lisp file? and what is the command, is it C-c C-c ? It would be great if you could make a web app tutorial from start to finish, going into the different files, making CSS changes, etc. Thank you!

[@simonced]

What a great explanation. I am quite new to common lisp, but why is that #:something we see everywhere? Also #''functionname was used as well.

[@GavinFreeborn]

There isn't really any difference. There may be an actual distinction for a style guide but they are treated the same by defpackage thing as far as I know.

[@GavinFreeborn]

Quick update. For the #: www.lispworks.com/documentation/HyperSpec/Body/02_dhe.htm is what you are looking for. Can't remember if I explained #'functionname (youtube won't show me) but it's basically saying we are refering to a function and not a variable. I have a video on emacs lisp that explains it. kzbin.info/www/bejne/hKDGdaBqr9-HpdE

[@josueteodoro2342]

hey, great content! In a different tangent, what modeline are you using in emacs?

[@GavinFreeborn]

I made it myself github.com/Gavinok/emacs.d/blob/main/lisp%2Fmodeline.el

[@josueteodoro2342]

@@GavinFreeborn nice! Thank you.

[@codingreaction7332]

9:49 Hi Gavin, i don´t understand the command for going to the definition of ´ningle, is that M - . ( alt + periot) ?? Ty

[@omfgcow]

yes, M - . then M - , to return

[@Aluna123]

I have an error with 12:25 code, I dont know how to put the lambda symbol so write lambda, is this could be the cause of the error?, or have the same effect if I put lambda symbol or not?, thanks for the videos, I was getting a error from slime when I installed so thanks to your video of sly solve that problem

[@EdouardTavinor]

You can just write the word "lambda". I think Gavin has a plug-in for his editor that displays the Greek letter when he writes the word lambda

[@trannusaran6164]

Thank you for the tutorial, Gavin! Excellent CL content as always :) Just wanted to add something I found out recently that may save you time when writing build.lisp scripts: you can tell asdf to make all lisp systems available in a directory of your choice! If you had your systems in a ~/projects dir, just make a file called projects.conf in the directory ~/.config/common-lisp/source-registry.conf.d/ and give it the contents: (:tree "/home/gavinok/projects/")

[@GavinFreeborn]

Thanks for sharing! I had heard about that before but hadn't actually given it a try. I'll have to add that config some time soon

[@doofmoney3954]

This just made things more confusing

[@GavinFreeborn]

I'm sorry to hear that. Where did the confusion start? I'd be happy to clarify

[@samieb4712]

What's this shell program you are using towards the beginning?

[@GavinFreeborn]

Are you talking about sly? It's an emacs plugin. The whole demo was done in emacs

[@winter_light]

@@GavinFreeborn But I thought lem was better than emacs. What happened mate?

[@GavinFreeborn]

@@winter_light never really said that just said I like the project and why I like it. There is still plenty of things lem needs to do to catch up. Still depend on emacs for org mode and sly had stickers which I use extensively.

[@winter_light]

@@GavinFreeborn Mate, I just tried to pull your leg. Keep doing the great work as usual and thanks for keeping us motivated.

[@AhmedShariffGplus]

what kind of stuff do you do with lisp? i love lisp, other than emacs, I haven't seen it being used alot. Just curious.

[@GavinFreeborn]

Personally I consider it good for nearly anything! I recently wrote a basic static site generator in lisp. For my last job I made a web service in lisp. I use lisp to program and control my window manager. I kinda use it for everything! Probably the biggest selling point for using it is how fast you can get a prototype going and start developing core features of an application.

[@AhmedShariffGplus]

That's pretty cool to know. I'd love to see how you tackle more problems with lisp both for daily tasks and maybe even professionally.

[@blakemcbride26]

I do not understand your starting point. Your first screen - what is it. It's not bash. It's not emacs. It's not lem. What am I looking at?

[@GavinFreeborn]

The only screen I can think you are referring to is the directory (shown in emacs's dired)

[@blakemcbride26]

@@GavinFreeborn Wow! I've been using emacs since the '90. Your use of dir-mode is incredible. I'll have to look into that. Thanks!

[@NS-bl5nu]

; compilation unit aborted ; caught 1 fatal ERROR condition ; Loading "ningle" "SYNTAX" is a package name, so it cannot be a nickname for "CL-SYNTAX".

[@danielarf4409]

Why was nobody talking about this deep eyes?

[@vaakdemandante8772]

If only the IDE was decent. Using REPL is so frustrating, thank god we don't have to program in LISP with punchcards anymore :/ I wish there were some tutorial how to use LISP with Visual Studio Code and get all the benefits of modern IDE. Ps I've programmed a bit in LISP in the past. It's an awesome language, though I'm not touching it with a 10 foot pole unless I can be productive in it from the get go.

[@GavinFreeborn]

There is lisp works but I've never tried it

[@bl1tz533]

This sucks bro
